Austria's presidential election will have to be repeated nationwide after reports of irregular ballot-counting, the Constitutional Court rules.
The decision hands a new chance to far-right candidate Norbert Hofer, who narrowly lost the run-off election in May to Green contender Alexander Van der Bellen by a margin of only 31,000 ballots.
Hofer's Freedom Party had challenged the election on grounds that ballots were opened, sorted or counted prematurely or without proper oversight in a majority of voting districts.
The decision "serves only to strengthen trust in our laws and our democracy," says the court's president, Gerhart Holzinger.
The new run-off election between Van der Bellen and Hofer will likely take place in late September or early October, the Interior Ministry has said.
